Gary Yao commented on FLINK-8949:
---------------------------------
I removed _"Watermarks for tasks with a high parallelism (>160) can now be
queried and displayed correctly in the web frontend."_ from the release notes.
Normally, the release notes contain important changes relevant for upgrading
from a previous version, such as breaking changes. We do not include all bug
fixes in the release notes, and I do not see how this one differs other from
other bug fixes. If you think otherwise, feel free to add the release note back.
> Rest API failure with long URL

> Key: FLINK-8949
> URL: https://issues.apache.org/jira/browse/FLINK-8949
> Project: Flink
> Issue Type: Bug
> Components: Runtime / REST, Runtime / Web Frontend
> Affects Versions: 1.4.2, 1.5.0, 1.6.4, 1.7.2, 1.8.2
> Reporter: Truong Duc Kien
> Assignee: Maximilian Michels
> Priority: Major

> Time Spent: 20m
> Remaining Estimate: 0h

> When you have jobs with high parallelism, the URL for a REST request can get
> very long. When the URL is longer than 4096 bytes, the REST API will return
> error
> {{Failure: 404 Not Found}}
> This can easily be seen in the Web UI, when Flink queries for the watermark
> using the REST API:
> {{GET
> /jobs/:jobId/vertices/:vertexId/metrics?get=0.currentLowWatermark,1.currentLowWatermark,2.currentLo...}}
> The request will fail with more than 170 subtasks and the watermark will not
> be displayed in the Web UI.
